Question

1. find the area of the shaded region. use 3 for π. 10 m 5 m

Explanation:

Step1: Calculate rectangle area

$A_{rect}=10\times5 = 50$ m²

Step2: Calculate circle area

Radius $r=\frac{5}{2}$ m, $A_{circle}=3\times(\frac{5}{2})^2=\frac{75}{4}$ m²

Step3: Calculate shaded - area

$A = A_{rect}-A_{circle}=50 - \frac{75}{4}=\frac{200 - 75}{4}=\frac{125}{4}=31.25$ m²

Answer:

$31.25$ m²
